i recently purchased a used gen 6, but i cannot get it to communicate with the ecu. the Accel screen loads up fine but when i click on "edit ecu" it just says "waiting for ecu response" im fairly certain theres nothing wrong with the ecu and its just a plug and play operation. i checked voltage at the serial port connector and it has the 5 volt reference when the key is on. ive tried several laptops, even a dinasoar with windows 98. anybody have any ideas?

what should the serial port settings be? ive tried changing the baud rate, but not sure what it should be. i got the ecu, cable, and the calmap on cd. ive tried downloading it from sights on the internet to both the c drive and to a floppy disk. the problem is deffinately in either my version of dos or in the serial port speed. i know the port works because its the laptop my friend uses for the FAST system in his camaro, but that runs from windows, not dos
I've had problems with the laptop running too fast (even old ones). With my latest POS laptop, I boot the computer with a dos disk, insert a calmap disk after it boots, and it works great. I'm pretty sure this is a windows 98 laptop too.
I am the person Matt bought the DFI from. I can Vouch this DFI is good! nothing wrong!! prior to my purchase, from my close friend, I physically verified functioning unit!
In order for calmap to communicate with the accel power processor, you need to be in windows " DOS Mode"
( IMPORTANT!!! FIRST VERIFY YOUR LAPTOP FLOPPY DRIVE LETTER) ( THIS LETTER IS WHERE THE FOLLOWING INFORMATION NEEDS TO BE TYPED, MOST PC'S USE DRIVE LETTER "A", AS THE FLOPPY DRIVE ASSIGNMENT)
Matt, you need to, make a dos start up floppy. this is done by inserting a floppy disk, than formatting it. than, you make a boot disc, out of the floppy you just " quick formatted" . you have calmap on floppy now? you boot the 98 laptop with the boot disk, than a prompt should come up like " A\: " , When this come up, you remove the boot floppy, and slide calmap floppy in. Where the " A\: " is you type Calmap, immediately after, with no spaces,after " A\: " . It should look similar to " A\:calmap" it should start calmap that way. I am sorry, i thought you knew what 'DOS" mode was. P.S. I do not know if you have to type Calmap.exe maybe.
By the way, you did piggy back the power processor, right? I believe, the power processor plugs into factory harness, than you car ecm plugs onto harness from the accel power processor. let me know if you need HELP!!!!!
S.A. Design books had just released a book on the DFI version 6 just about the time Acell released version 7. It was authored by Ray Bochazes (spell?). I would say from the way he talks it's clear he has alot of hands on experience. I bought mine on e-bay it's a vary good book, vary clear and detailed.
That reminds me I was told to use windows 98 if at all possible and an older laptop something about the speed of the accel CPU. The little I know about computer hardware, let alone software can be put on the head of a vary small pin the room to spare. This was a response to an E-mail question sent to there on line help.
faster then your thirdgen
